My goal is to provide a thorough, expert perspective to help serious buyers - whether budding enthusiasts or seasoned professionals in need of a compact backup - make an informed choice.

A Tale of Two Compact Cameras: Design and Ergonomics

Form Factor and Build: Compactness vs. Handling

At a glance, the Olympus XZ-1 and Sony T90 could not be more different in their physical approach. The XZ-1 is a compact camera with those classic “enthusiast” touches, offering a robust magnesium alloy body with dimensions of 111 x 65 x 42 mm and a weight of 275 g (without battery or card). This size, while portable, is larger and chunkier than the Sony T90, which is categorized as an ultracompact, measuring a mere 94 x 57 x 15 mm and weighing only 148 g.

The Sony’s ultra-slim profile almost feels like holding a high-end smartphone, optimized for pocketability and discreet shooting. However, the thin design compromises grip security and tactile feedback during manual adjustments. Conversely, the XZ-1’s thicker body and pronounced front grip better support one-handed shooting stability and quicker manual control access.

This ergonomic dichotomy is epitomized in the control layout and handling comfort. Olympus integrates dedicated dials for shutter speed, aperture, and exposure compensation on the XZ-1, reflecting its photo enthusiast orientation. In contrast, Sony’s T90 leans towards minimalism with fewer physical controls, relying more on touchscreen interface and simplified menu navigation.

Ergonomic Verdict: For photographers who crave precise manual input and a reassuring grip, especially when shooting in dynamic conditions, the Olympus XZ-1’s body design and control layout provide a clear advantage. However, if your priority is sheer portability, unassuming street photography, or easy carry on travel, the Sony T90’s ultracompact form is extremely compelling.

Sensor Technologies and Image Quality Dive

A critical determinant of any camera’s photographic capabilities lies beneath the hood: the sensor. The Olympus XZ-1 features a 1/1.63-inch CCD sensor sized 8.07 x 5.56 mm with a diagonal of roughly 1/1.63", compared to the Sony T90’s smaller 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm.

This sensor size difference translates into a sensor area of approximately 44.87 mm² for the Olympus versus 28.07 mm² for the Sony, nearly a 60% increase in sensor surface capturing light and detail. More surface area directly benefits low-light performance and dynamic range since larger photosites typically gather more photons and reduce noise, especially at higher ISOs.

While the Sony’s sensor resolution sits at 12 megapixels with max image size of 4000 x 3000 pixels, the Olympus chooses a slightly lower native resolution of 10 megapixels (3664 x 2752 pixels). This deliberate design enables Olympus to emphasize per-pixel quality and noise control over sheer pixel count, supporting its goal to optimize high ISO usability and low-light shooting.

A measured DXOMark score backs these sensor distinctions, with the Olympus scoring:

• Overall: 34 points
• Color Depth: 18.8 bits
• Dynamic Range: 10.4 EV
• Low-Light ISO: 117 (better performance at elevated ISO)

The Sony T90 was not formally tested by DXOMark, but given the smaller sensor, lower lens aperture, and older CCD technology, its real-world image quality likely falls short of the XZ-1’s, especially in shadow detail and noise performance.

Image Quality and Sensor Analysis: Olympus markedly leads in sensor sophistication, particularly in light sensitivity and dynamic range, giving the XZ-1 a technical edge for photographers prioritizing image fidelity, dynamic scenes, and usable noise performance at elevated ISO settings.

Display and Viewfinder: Interaction and Image Review

Both cameras feature a fixed 3-inch LCD for framing and image review. However, their engagement differs:

• The Olympus XZ-1 offers a 3-inch OLED display with a resolution of 614k dots, significantly sharper and more vivid, especially under varying light conditions.
• The Sony T90 employs a standard LCD with 230k dots, which appears noticeably less detailed and less bright in daylight or high-contrast outdoor scenes.

Neither camera includes a built-in electronic viewfinder; the Olympus has an optional EVF accessory, whereas the Sony provides none, which could bother shooters in bright sunlight where LCD visibility degrades.

Moreover, the Sony T90 supports a touchscreen interface, while the Olympus uses physical buttons and dials without touch input. The touchscreen on the Sony simplifies menu navigation and selecting focus points but may be challenging in some shooting situations (e.g., with gloves or in rain).

Display and Usability Note: For photographers who value accurate image preview and reliance on physical controls, the Olympus screen and its dedicated buttons deliver a better experience. Sony’s touchscreen is user friendly for casual mix-and-match shooting but limited by its lower resolution screen.

Lens Optics and Focus Systems: Versatility vs. Speed

Lens Specifications and Aperture

The Olympus XZ-1 sports a built-in 28-112 mm f/1.8-2.5 lens, boasting one of the fastest apertures available in a compact zoom camera at retail price. The bright f/1.8 at wide-end allows exceptional light-gathering, enabling creative shallow depth-of-field effects and better responsiveness in low light. The 4x optical zoom range covers a versatile scope from wide-angle to short telephoto.

The Sony T90’s lens covers 35-140 mm focal range at f/3.5-10.0 aperture, slower and narrower at the wide end, with a notably slower telephoto aperture of f/10, which limits low-light usability and bokeh control.

Autofocus and Speed

Olympus implements a contrast-detection AF with 11 focus points plus face detection and AF tracking. While contrast detection is generally slower than phase detection, the Olympus autofocus system on the XZ-1 handles single AF reasonably well and tracks simple faces effectively. However, continuous AF and tracking performance are limited, reflecting its 2011 technology vintage.

Sony’s T90 incorporates 9 contrast detection AF points with multi-area focusing but lacks face detection and tracking. Its AF speed is moderate but hampered by the small sensor and narrow aperture lens, which provides less information for focusing algorithms in dimmer situations.

Macro Capabilities

The Olympus XZ-1 shines in macro photography with a close focus distance as near as 1 cm, enabling extreme close-ups with excellent sharpness and separation from background. The Sony does not specify macro focus specs, and the slower lens limits close-up creative options.

Lens and AF Conclusion: The Olympus lens and AF system provide a clear advantage in flexibility and creative potential. The wider aperture coupled with macro capability makes it vastly superior for portraits, low light, and detailed close-ups. Sony’s package is more oriented toward casual snapshots with a stronger telephoto reach but narrower apertures.

Burst Shooting and Shutter Speed Range: Action Versatility

Continuous shooting speed and shutter range also weigh heavily for sports, wildlife, and dynamic capture.

• Olympus XZ-1 offers a shutter speed range of 1/60 sec to 1/2000 sec in mechanical shutter and 2 fps continuous photography.
• Sony T90’s shutter speeds range from 1 sec to 1/1600 sec, also with 2 fps burst.

Both offer low burst speeds by modern standards with neither designed for high-speed action. The Olympus’s slightly longer max mechanical shutter speed is a marginal plus for bright daylight photography with wide apertures.

Exploring Real-World Photography Applications

Portrait Photography

The Olympus’s fast f/1.8 lens and accurate skin tone rendering from the sensor - backed by face detection autofocus capabilities - make it better suited for portraits, particularly in natural light or interior environments. Its macro focus ability permits intimate portraits with tight detail on facial features or accessories.

The Sony T90’s slower lens and lack of face detect AF render it less adept for artistically blurred backgrounds or selective focus, though it remains capable for environmental portraits or snapshots.

Landscape Photography

For landscapes, the XZ-1’s broader dynamic range (10.4 EV) preserves details in shadows and highlights, critical for scenes with varying exposure zones like skylines or forests. Its wider 28 mm equivalent focal length captures vast vistas better than Sony’s 35mm start. Unfortunately, neither camera offers weather sealing, limiting use in harsh conditions.

Wildlife and Sports

Neither camera can rival DSLR or advanced mirrorless systems for professional wildlife or sports photography due to limited autofocus speed and low burst rates. However, Olympus’s better AF tracking and brighter lens give it a slight edge for casual wildlife shots in daylight.

Street Photography

Sony T90’s compact form factor and quiet operation make it ideal for street photography where discretion is key. The slim profile minimizes attention and the fast wake-up times aid spontaneous shooting, despite slower AF. Olympus is noticeably bigger and more conspicuous but offers higher image quality.

Macro Photography

Olympus XZ-1’s remarkable 1 cm close focusing coupled with fast lens makes it a standout choice for macro enthusiasts desiring portability. Sony’s lack of macro precision diminishes its appeal in this niche.

Night and Astro Photography

Thanks to the larger sensor and brighter optics, the Olympus delivers better high ISO performance and cleaner exposures in low light or astrophotography, despite the lack of dedicated bulb modes or intervalometers. Sony’s smaller sensor produces noisier images in similar conditions.

Video Capabilities

Both models offer 720p HD video recording at 30 fps in Motion JPEG format - standard for the era but outdated by today’s standards - with no external microphone or headphone jacks for audio monitoring. Olympus’s sensor shift (sensor-shift) image stabilization benefits shaky handheld video, whereas Sony’s optical image stabilization helps but cannot compensate for the smaller sensor’s noise tendencies.

Connectivity, Storage, and Battery Life

Both cameras lack wireless connectivity - no Wi-Fi, Bluetooth, or NFC. This omission is notable given the emerging user demand for instant sharing and remote control even at their launch periods. Both use USB 2.0, with the Sony supporting proprietary Memory Stick Duo / Pro Duo media and the Olympus relying on standard SD/SDHC/SDXC cards, favoring greater media compatibility.

Battery life is moderately comfortable on Olympus with ~320 shots per charge, tested using the Li-50B pack. Sony does not specify battery details, a downside for serious users needing consistent power assurance.

User Interface and Overall Handling

Beyond physical ergonomics, the Olympus’s more extensive manual exposure modes (including shutter/priorities and manual aperture control) appeal strongly to enthusiasts wishing to learn and experiment with exposure control. Sony T90 lacks shutter or aperture priority modes, simplifying operation at the expense of creative flexibility.

Pricing and Value Analysis

At retail pricing, the Olympus XZ-1 hovers around $567, nearly double the Sony Cyber-shot T90 at $258. While the Olympus commands a premium, this cost reflects superior optics, sensor capability, robust handling, and creative functionality.

For budget-conscious users who want an ultra-portable camera for everyday snapshots and casual travel, the Sony T90 offers excellent value but with limitations in creative control and image quality.
